IRA WARREN, OF BOSTON, MASSACHUSETTS.

SHOWER-SYRINGE.

Specification of Letters Patent No.

To all 'whom it may concern:

Be it known that I, IRA WARREN, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful surgical instrument or shower syr-v inge foi` the more efficacious and less painful use or topical medicatio-n as applied to the pharynx and air-passages, and that the following description, taken in connection with the accompanying drawings, hereinafter referred to, forms a full and exact specification of the same, wherein I have set forth the nature and principles of my said inVent-ion, by which it may be distinguished from others of a similar class, together with such parts as I claim and desire to have secured to me by Letters Patent.

i The instrument which has hitherto been employed, consists of a piece of whalebone,

bent at one end, to which is attached a small piece of sponge which is dipped in a proper solution and applied directly to the diseased part. But in cases where the parts are much infiamed, the muscles sufer great irritation from the Sponge of'the above instrument or probang.

These de-fects I have 'remedied by my improved instrument, which consists of a syringe, to which is attached a tube, which may be bent or straight according to the purpose for which it is to be used, and having on its end a small hollow globe full of fine holes, through which can be ejected, by

'means of the syringe, a solution of nitrate of silver, or other proper substances, for the purpose 'of w'ashing the sidesof the pharynx, larynX &c. I

The. advantages of my instrument .are that the bulb being' small and smooth it can be introduced into an infiamed cavit-y causing much less irritation than the sponge of the probang and the muscles cannot clin to it upon its withdrawal.

y instrument also washes all sides of the cavity much better than the Sponge, by jetting the contained solution in all directions',

while it will reach much farther than the probang with less sufl'ering on the part of the patient.

The figures of the accompanying plate 01' drawings represent the different forms of myV instrument.

Figure lis a central longitudinal section of the pharyngeal shower syringe, or instrument for washin' the upper pa-rt of the th'roat. bb is the lmrrel of the syringe, ancl co the piston rod.' To this is attached a small, straight tube dd with a globe e at` the end, with fine holes pierced in it from the outer end to the center.

F ig. 2 is a central longitudinal section of the laryngeal shower syringe, 01' instrument for washing the walls of the larynx. It has a syringc bb-cc to which is attached a small bent tube ff with a globe e at the end pierced with a strip or belt of fine holes. A

single jet from the syringe Will throw a very fine stream throughV each of the holes in the globe andv Wash all sid'es of the walls of thelarynx. o

Fig. 3- is a central vlongitudinal section of the nasal show'er syringe or instrument .for washing the back'passages to the nose. It is constructed, like the others, of a syringe bb-oc and has a. bent. tube gg attaohed to it with a globe e at the end pierced with fine holes at the upper end. y

Having thus described my shower syringes, I shall state my claim as follows.

What I claim as my invention and 'desire to have secured to me by Letters Patent, as a new and useful surgical instrument for thetreatment of diseases of the air ,passages of the throat and nose, is-

Thef above syringe construoted of the form and of the Vmaterials described, for the objects set forth.
